Wilder has KO'd 39 of his 40 professional opponents while Fury has been down twice in his career.

But he frustrated Klitschko for 12 rounds before the judges gave him the nod on a famous night three years ago.

And Lewis added: "It should be exciting and explosive because styles make fights. So it's a question of which style wins? Neither of them has faced an opponent like the other before.

"Wilder hasn't been in with anyone as mobile as Fury, so can he catch him? Tyson won't find it as easy to avoid Deontay as he did Wladimir because this guy can move and throw. And as I say Wilder doesn't have to punch you on the chin or temple to knock you out.

"When he hits anyone in the world anywhere on the head down they go, concussed. How will Fury react? He's proved he's a survivor in the past but will he be able to get up again from something this heavy?

"On the other hand, how will Deontay deal with Tyson taking the Mickey in the very serious business of heavyweight boxing? With Fury it's catch me if you can. It's now you see my face, now you can't hit it. Wilder could get too frustrated. It's impossible to know the outcome."
